Outline of Final Research Achievements

The experimental tests of one-bay frame with mullions formed in non-structural wall to investigate behavior of mullions formed in non-structural reinforced concrete walls were carried out. The main findings can be summarized as follows: flexural behavior and shear behavior dominate in mullions in accordance with flexural bending behavior of wall and; axial force of mullions increase correspond to increase of drift which might lead to shear failure even if sufficient shear reinforcement are arranged. The failure mechanism assumed considering axial forces acts on mullions is agreed with experimental results.
